Trump’s budget eliminates ARPA-E altogether. It also eliminates the spectacularly successful $70 billion loan program. It cuts funding to the national labs in a way that implies the laying off of 6,000 of their people. It eliminates all research on climate change. It halves the funding for work to secure the electrical grid from attack or natural disaster. “All the risks are science-based,” said John MacWilliams when he saw the budget. “You can’t gut the science. If you do, you are hurting the country. If you gut the core competency of the D.O.E., you gut the country.”
